[8.09] Stellar Magnetic Activity, the Earth and Exoplanets: How Future Space Missions Can Contribute to Understanding Solar Activity and Solar-terrestrial Influences

S.L. Baliunas, W.W.-H. Soon (CfA/MWO)

The solar spectral and particle output varies over time scales of minutes to eons; some of those variations are documented or claimed to have influenced the terrestrial environment. The origins of solar variability include the progress of fusion through time and the complex interaction of the interior gas and magnetic fields. The Mount Wilson HK Project has yielded information on stellar magnetic activity on more than 2,000 stars going as far back as 38 years in order to put solar magnetic activity in a physical perspective unavailable from theory and models alone. We discuss how future space missions like Space Interferometry Mission (SIM) and Stellar Imager (SI) would contribute to understanding solar variability that has influenced -- and should continue to influence -- life and the environment on earth.

This research funded in part by MIT-MSG 5710001241, JPL 1236821, AF 49620-02-1-0194, a grant from NASA HQ and GSFC to SAO for the SI Vision Mission Study, NASA NAG5-7635, NRC COBASE, CRDF 322, Richard Lounsberry Foundation, Langley-Abbot, Rollins, Scholarly Studies and James Arthur Funds (Smithsonian Institution) and several generous individuals.
